High Voltage Current Limiting Fuses
- CLF (25.8kV High Voltage Current Limiting Fuses)
- 25.8kV High Voltage Current Limiting Fuses is economically effective and carries excellent break performance which is widely used along with other protective equipment to protect high-pressure circuits and high-voltage equipment (e.g. current transformers, condensers, etc.) from overcurrent or short-circuit current. This light weight product has a high-capacity breaking performance of 40㎄ and is optimal for protecting power receiving circuits and equipment.
Product Attributes
- •This product is made in Korea using 100% local technology and equipment.
- •First product in Korea developed using the KEPCO standard voltage(25.8㎸)
- •First in Korea to develop a non-standard compact size (reduced the fuse length by 23% to 342㎜)
- •Adopts polymer base insulator
